What is the main advantage of using zebrafish for metabolic studies?
Zebrafish allow for the study of whole organism metabolism, providing a comprehensive view of mitochondrial function compared to cell-based assays.
How does the Seahorse XF 24 analyzer work?
It measures the oxygen consumption rate and extracellular acidification rate to assess cellular respiration and metabolic activity.
What types of manipulations can be performed on zebrafish embryos?
Genetic modifications and pharmacological treatments can be applied to study their effects on metabolism.
Why is it important to use embryos at the same developmental stage?
Using embryos at the same stage ensures consistent results when comparing metabolic profiles between control and treated groups.
What are the implications of increased lipid deposition in treated embryos?
Increased lipid deposition may indicate altered metabolic pathways and can provide insights into the effects of specific treatments on metabolism.
